Problem description

This kernel update fixes the following security problems:
  • CVE-2008-0007: Insufficient range checks in certain fault handlers could be used by local attackers to potentially read or write kernel memory.
  • CVE-2008-0001: Incorrect access mode checks could be used by local attackers to corrupt directory contents and so cause denial of service attacks or potentially execute code.
  • CVE-2007-5966: Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 allows local users to execute arbitrary code or cause a denial of service (panic) via a large relative timeout value. NOTE: some of these details are obtained from third party information.
  • CVE-2007-6417: The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear allocated memory in some rare circumstances, which might allow local users to read sensitive kernel data or cause a denial of service (crash).
Additionally the following bugfixes have been included for all platforms:
  • patches.suse/bootsplash: Bootsplash for current kernel (none). patch the patch for Bug 345980.
